KSA-based Arithmetic. pLUTo enables addition using the Kogge-Stone Adder (KSA) approach demonstrated in prior work [1]}, [2]}.
KSA performs carry-look-ahead addition with only XOR, AND, and shifting operations. pLUTo can also perform subtraction (two's complement) by either 1) a single pLUTo LUT Query, or 2) an Ambit-NOT [3]} operation and an increment operation.
